With reference to FIG. 1, a plurality of containers or storage assemblies 10, for storing bulk items or powders, for example, protein powders, is shown in various states of assembly and use, such as folded for storage or expanded for use. In some embodiments, the storage assembly 10 may be configured and dimensioned for storing various substances (e.g., liquid foods, solid foods, non-food items and/o bulk food/non-food products). The storage assembly 10 generally includes an outer box or outer container 12 and an inner container 14 disposable within the outer box 12. The outer box 12 is of a rigid construction to provide integrity to the storage assembly 10 and is transitionable between an expanded state, as shown in FIGS. 2A-6B, and a collapsed state, as shown in FIGS. 7 and 8.

With reference to FIGS. 2A-10, the outer box 12 may be fabricated from cardboard or any other suitable material capable of maintaining its shape when devoid of any material contained in the inner container 14 of the storage assembly 10. The outer box 12 of storage assembly 10 is rectangular and capable of holding approximately 3 pounds of materials therein. In some embodiments, the outer box 12 may assume any suitable shape, such as, for example, square, circular, oblong, triangular, cylindrical, or the like, and may be capable of holding more or less than 3 pounds of materials. The outer box 12 is approximately 6 inches in width and approximately 9.5 inches in height. In other embodiments, the outer box 12 may have a width of between about 1 inch and about 12 inches and a height of between approximately 5 inches and about 20 inches. It is contemplated that the outer box 12 may have any suitable dimensions.

The outer box 12 has a bottom portion or main body 16 and a top, lid, or cover 18 pivotably attached to the main body 16. The main body 16 defines a cavity 17 (FIG. 9) therein dimensioned for receipt of the inner container 14 when the inner container 14 is in either an expanded or collapsed state. As best shown in FIGS. 6A, 7, and 8, the main body 16 has a plurality of side walls 20 a, 20 b, 20 c, 20 d coupled to one another. In particular, the side walls 20 a-d are coupled to one another at seams or joints that allow the side walls 20 a-d to bend relative to an adjacent side wall 20 a, 20 b, 20 c, or 20 d between an expanded state (FIGS. 2A-6B), in which the side walls 20 a-d are bent at approximately 90 degrees relative to one another to form a rectangular shape, and a collapsed state (FIGS. 7 and 8), in which the side walls 20 a-d are coplanar and/or parallel.

With continued reference to FIGS. 6A-8, the main body 16 further includes a first end or bottom end and a second end or top end spaced longitudinally from the bottom end. The first end, which forms the base of the main body 16, defines a depression or pocket 19 therein. The pocket 19 is defined by a recessed bottom wall 22 of the main body 16 and four inner side walls 24 a, 24 b, 24 c, 24 d of the main body 16. The pocket 19 of the main body 16 is dimensioned to receive a lid 34 ¹ of an inner box 14 ¹ of another storage assembly 10 ¹ such that two or more storage assemblies 10, 10 ¹ may be stacked on top of one another in a vertical orientation, as shown in FIG. 6B.

With reference to FIGS. 7-10, the second end or top end of main body 16 of the outer box 12 has a pair of foldable flaps 26 a, 26 b each extending from a respective, opposing side wall 20 a, 20 c of the main body 16. In some embodiments, more than two of the side walls 20 a-d of the main body 16 may have a flap 26 a, 26 b. Each of the flaps 26 a, 26 b defines an arcuate cutout 28 a, 28 b in a free end thereof. When the flaps 26 a, 26 b are in a folded state (e.g., when the flaps 26 a, 26 b are perpendicular to their respective side walls 20 a, 20 c), the arcuate cutouts 28 a, 28 b of each of the flaps 26 a, 26 b collectively define an annular opening (not explicitly shown). The annular opening is dimensioned to allow for a top 34 of the inner container 14 to protrude therethrough. In addition, when the inner container 14 is disposed within the outer box 12, the flaps 26 a, 26 b are received under the lid 34 (or an annular ring or neck 36) of the inner container 14 such that the flaps 26 a, 26 b prevent or inhibit the lid 34 of inner container 14 from falling through (or collapsing into) the annular opening and into the cavity 17 of the main body 16 of the outer box 14. As such, the flaps 26 a, 26 b maintain the lid 34 of the inner container 14 above the lid 18 of the outer box 12 so that the lid 34 of the inner container 14 remains accessible by a user.

Each wall 20 a-d of the main body 16 of the outer box 12 has a flap 29 a-d disposed at a bottom end thereof for detachably interlocking with one another to selectively close the bottom end of the main body 16 of the outer box 12. The flaps 29 a-d together define the recessed bottom wall 22 of the main body 16 (see FIG. 6A). Each of the flaps 29 a-d is pivotably coupled to the bottom end of the respective wall 20 a-d via a strip or tab 31 a-d. The tabs 31 a-d may have a substantially rectangular configuration and may be folded into the cavity 17 of the main body 16 of the outer box 12 to define the inner side walls 24 a-d of the main body 16 (see FIG. 6A). Upon folding the tabs 31 a-d inwardly into the cavity 17 of the main body 16 of the outer box 12, the recessed bottom wall 22 defined by the flaps 29 a-d of the main body 16 and the inner side walls 24 a-d defined by the tabs 31 a-d of the main body 16 together form the pocket or recess 19 in the bottom end of the main body 16 of the outer box 12.

The lid 18 of the outer box 12 is pivotably connected to one side wall 20 b of the main body 16 to selectively cover the cavity of the main body 16. In some embodiments, the lid 18 may be detachable from the main body 16. The lid 18 defines a central opening 30 therethrough dimensioned for receipt of a top or lid 34 of the inner container 14 and to prevent removal of the main body 32 of the inner container 14 from the cavity of the outer box 12. The central opening 30 of the lid 18 defines a central axis therethrough that is coaxial with a central longitudinal axis defined through the main body 16 of the outer box 12. As shown in FIG. 4B, the lid 18 has at least one tab 21 extending downwardly therefrom and dimensioned for releasable receipt in a notch 13 defined in a side wall of the main body 16 (e.g., side wall 20 a) of the outer box 12.

With reference to FIGS. 2A-5, 9, and 10, the inner container 14 of the storage assembly 10 has a flexible, collapsible main body 32 and a lid 34 removably attached to the main body 32. The main body 32 defines a cavity therein configured for receipt of food materials, such as, for example, protein powders, or any other suitable material whether liquid, solid, powder or gas, food and/or non-food. The main body 32 of the inner container 14 is fabricated from bonded layers of aluminum and plastic such that the main body 32 of the inner container 14 can be flattened when the cavity of the inner container 14 is devoid of stored materials. In some embodiments, the main body 32 of the inner container 14 may be fabricated from various food-grade plastic materials, such as, for example, polypropylene, polyester, polylactide, polyethylene terephthalate, and/or polystyrene, and may be opaque. The main body 32 of the inner container 14 is manufactured by molding or heat sealing a plurality of walls together. The main body 32 is designed such that upon filling the cavity of the main body 32 with liquid, particles, or powder, the main body 32 assumes a substantially rectangular shape or cube shape dimensioned for receipt in the cavity of the main body 16 of the outer box 12. In some embodiments, the main body 32 of the inner container 14 may assume a variety of shapes (e.g., triangular, square, circular, or the like) and may be of a monolithic construction rather than consisting of a plurality of walls sealed to one another. The lid 34 of the inner container 14 may assume a variety of sizes and shapes (e.g., triangular, circular, square, or the like).

The main body 32 may have a top wall 33 fabricated from a more rigid material than the remainder of the main body 32 so that the top wall 33 maintains a planar configuration when the inner box 14 is in either of the collapsed or expanded states. The main body 32 of the inner container 14 also includes a plastic annular ring 36 of a rigid construction that forms an opening of the main body 32. In embodiments, the plastic annular ring 36 may be formed with or coupled to the top wall 33 of the main body 32. The plastic annular ring 36 defines an outer threading configured for threading engagement with an inner threading of the top or lid 34 of the inner container 14. In some embodiments, the lid 34 of the inner container 14 and the annular ring 36 of the inner container 14 may be detachably coupled to one another via any suitable fastening engagement, such as, for example, snap-fit. The annular ring 36 also defines an annular lip or flange 37 configured for receipt of the flaps 26 a, 26 b of the main body 16 of the outer box 12. As noted above, when the inner container 14 is disposed within the outer box 12, the flaps 26 a, 26 b of the outer box 12 are received under the lip 37 of the annular ring 36 to prevent the lid 34 of the inner container 14 from falling, due to gravity, into the outer box 12. As such, the lid 34 of the inner container 14 remains protruding from the lid 18 of the outer box 12.

In use, as shown in FIG. 1, a plurality of storage assemblies 10 is provided. Initially, the main body 16 of the outer container 12 of each of the storage assemblies 10 is collapsed by folding each of the walls 20 a-d thereof about their seams. With the outer containers 12 in a collapsed state, each of the outer containers 12 may be stacked, either horizontally or vertically. The main body 32 of the inner container 14 of each of the storage assemblies 10 is also collapsed. Since the top wall 33 of the main body 32 may be more rigid than the remainder of the main body 32, the top wall 33 may remain planar when the main body 32 is in its collapsed state. With the inner containers 14 in a collapsed state, each of the inner containers 14 may be stacked, either horizontally or vertically. In embodiments, a collapsed inner container 14 may be stacked with a collapsed outer container 12 by positioning the lid 34 of the inner container 14 through the opening 30 in the lid 18 of the outer container 12.
